THERMAL PROPERTIES AND ESTIMATED GLYCEMIC INDEX OF DIFFERENT COMPOSITE FLOURS AND THEIR GLUTEN-FREE BREAD MAKING PERFORMANCES

This study aimed to investigate thermal properties and estimated glycemic index of various gluten-free flours (rice, chestnut, chickpea and bean). Gluten-free bread was prepared by mixing chestnut, chickpea and bean flours with rice flour at different ratio (0:100, 25:75, 50:50) using straight dough bread making process. Bean flour reflected the lower estimated glycemic index as compared to the other gluten-free flours. The chestnutrice flour (50:50) bread exhibited the highest texture firmness after 8 days of storage, followed by the rice flour bread. Chestnut-rice flour (25:75) bread was the swellest comparatively. Future studies may be focused on developing the sensorial characteristics of gluten-free breads prepared from chickpea and bean flours.
